Description
Die vorliegende Erfindung betrifft eine Frischgasversorgungsanlage für eine Brennkraftmaschine, insbesondere eines Kraftfahrzeugs, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The present invention relates to a fresh gas supply system for an internal combustion engine, in particular a motor vehicle, with the features of the preamble of claim 1.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Frischgasversorgungsanlage der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine verbesserte Frischgaszuführung zu den Zylindern auszeichnet.The The present invention addresses the problem of for a fresh gas supply system of the aforementioned Art to provide an improved embodiment, which in particular by an improved fresh gas supply distinguishes to the cylinders.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, den Einlassabschnitt des Einzelrohrs in zwei parallele Abschnitte, nämlich einen Haupteinlassabschnitt und einen Nebeneinlassabschnitt zu unterteilen, die sich durch unterschiedlich lange Strömungswege voneinander unterscheiden. Desweiteren ist die Schaltklappe so ausgelegt, dass sie in der Drehmomentstellung nur den Haupteinlassabschnitt aktiviert, während sie in der Leistungsstellung dem Nebeneinlassabschnitt hinzuschaltet, so dass in der Leistungsstellung beide Einlassabschnitte parallel aktiv sind. Da der Nebeneinlassabschnitt kürzer ist als der Haupteinlassabschnitt, wirkt in der Leistungsstellung eine kleinere Rohrlänge als in der Drehmomentstellung. Gleichzeitig führt die Aktivierung sowohl des Haupteinlassabschnitts als auch des Nebeneinlassabschnitts dazu, dass für den Transport von Frischgas zum Auslassabschnitt ein größerer Strömungsquerschnitt zur Verfügung steht. Hierdurch wird der Strömungswiderstand des jeweiligen Einzelrohrs in der Leistungsstellung reduziert, was die Befüllung des jeweiligen Zylinders unterstützt und insgesamt die Leistungsfähigkeit der mit der Frischgasversorgungsanlage ausgestatteten Brennkraftmaschine verbessert.The Invention is based on the general idea, the inlet section of the single tube into two parallel sections, namely one Subdivide the main inlet section and a sub-inlet section, which are separated by flow paths of different lengths differ. Furthermore, the switching flap is designed so that it activates only the main inlet section in the torque position, while in the performance position the sub-inlet section hinzuschaltet, so that in the power position both inlet sections are active in parallel. As the sub-inlet section becomes shorter is considered the main inlet section, works in the power position a smaller pipe length than in the torque position. At the same time the activation of both the main inlet section leads as well as the sub-inlet section to that for the Transport of fresh gas to the outlet section a larger flow cross-section is available. As a result, the flow resistance the respective single tube in the power position reduces what the Filling the respective cylinder supports and overall the performance of the fresh gas supply system equipped internal combustion engine improved.
Die erfindungsgemäße Frischgasversorgungsanlage lässt sich bei einer bevorzugten Ausführungsform besonders einfach dadurch realisieren, dass der Haupteinlassabschnitt und der Nebeneinlassabschnitt bis zur Schaltklappe durch eine gemeinsame, in den Frischgasverteiler hineinragende Trennwand voneinander getrennt sind. Hierdurch lässt sich in einem gemeinsamen Rohrkörper durch Einfügen der Trennwand der durchströmbare Querschnitt des Rohrkörpers in den Haupteinlassabschnitt und den Nebeneinlassabschnitt unterteilen. Besonders vorteilhaft ist dabei eine Weiterbildung, bei welcher die Schaltklappe in der Drehmomentstellung besagte Trennwand bis zum Auslassabschnitt verlängert. Im gemeinsamen Rohrkörper bilden somit in der Drehmomentstellung die Trennwand und die Schaltklappe zusammen einen Wandungsabschnitt, der sich vom Haupteinlass bis zum Auslassabschnitt erstreckt.The inventive fresh gas supply system leaves in a preferred embodiment particularly simple realized by the main inlet section and the secondary inlet section to the switching flap through a common, in the fresh gas distributor protruding partition are separated. This leaves Insert in a common pipe body the partition of durchströmbare cross section of the tubular body into the main inlet section and the sub-inlet section. Especially advantageous is a development in which the switching flap in the torque position said partition extended to the outlet section. In the common tubular body thus form in the torque position the partition and the switching flap together a wall section, the extends from the main inlet to the outlet section.
Besonders vorteilhaft ist eine Weiterbildung, bei welcher die Schaltklappe in der Leistungsstellung an einer Wandung des Nebeneinlassabschnitts anliegt oder insbesondere in dieser Wandung versenkt angeordnet ist. Auch diese Ausführungsform senkt den Strömungswiderstand des jeweiligen Einzelrohrs. Gleichzeitig wird bei dieser Bauweise der wirksame Strömungswiderstand im aktiven Teil des Einzelrohrs reduziert.Especially advantageous is a development in which the switching flap in the power position on a wall of the Nebeneinlassabschnitts rests or arranged sunk in particular in this wall is. This embodiment also reduces the flow resistance of the respective single tube. At the same time, this construction method the effective flow resistance in the active part of the single tube reduced.
Weitere wichtige Merkmale und Vorteile der erfindungsgemäßen Frischgasversorgungsanlage ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Further important features and advantages of the invention Fresh gas supply system result from the subclaims, from the drawings and from the associated description of the figures based on the drawings.
